摘要。基于触摸的手机和平板电脑已经开始带有内置的辅助功能，促进了残疾人的融入。特别是，盲人可以使用这些设备，通常借助于屏幕阅读软件以及无痛的探索方法。然而，对于很大一部分人来说，第一次接触这些设备仍然具有挑战性，未来由触摸表面统治的前景令人生畏。这些小工具的成功程度各不相同，并且高度依赖于用户的能力。为了方便盲人使用移动设备，需要更好地理解触摸界面的需求。在本文中，我们提出了一项研究，41名盲人在不同的设备上执行低水平的目标获取任务。结果显示，设备尺寸的差异和物理边界的简单添加可能会深刻影响用户的性能。应进一步探讨这些差异，以促进包容。
Abstract. Touch-based mobile phones and tablets have started to be shipped with built-in accessibility features, fostering the inclusion of disabled people. Particularly, blind people can use these devices resorting to screen reading software commonly along with a painless exploration approach. However, for a large part of the population, a first approach to these devices is still challenging and a future reigned by touch surfaces presents as daunting. The success with such gadgets varies and is highly dependent on the user’s abilities. To ease a blind person’s experience with mobile devices a better understanding of touch interface demands is required. In this paper, we present a study with 41 blind people where they performed low-level target acquisition tasks with different devices. Results revealed that differences in device size and the simple addition of a physical border are likely to deeply affect user performance. These differ-ences should be further explored to foster inclusion.
